Reading progress update: I've read 30%.

The Dark Tower, Volume 3: Treachery - Peter David, Stephen King, Richard Ianove, Jae Lee, Robin Furth

Chapter two was a dud. And we have a character introduced that I don't recall from the books, Aileen. She wants to be a Gunslinger. She changes the Gunslinger motto and it felt...off. Anyway this chapter read as filler.
